Alternate for Showmodaldialog in mozilla firefox

Hi all.
I have used showmodaldialog for a popup window. it works fine in IE but shows :Error: showModalDialog is not defined.
I have gone through many forums but haven't got satisfactory solution.

Moreover i dont want the popupwindow to be closed manually .It gets closed automatically as the time fixed for its display gets over.

This functionality is working fine in IE but if someone could help me out to run it in Mozilla and other browsers,it would be great.

Below is my code:

[HTML]function getUpload(sForm){
var synclose=null;

var sURL = sForm;
var rst = showModalDialog(sURL, '', 'dialogWidth:600px; toolbar:0; dialogHeight:300px; status:0; resizable=0;');
<body onLoad="getUpload('syncpop.php')"> </body>


//Here is the syncpop.php page

<? $mode=1;
if ($mode==1){?>
<script language="javascript">
document.write("Synchonizing, please wait...");
<? }
<script type="text/javascript">
alert('Last Synchronizaton completed successfully');
window.returnValue = "Success!!";
<? }?></body>

The code involves a little bit of php but it hardly makes difference..i want the javascript function only that could solve my above mentioned purpose.

Thanks and Regards

for other browsers you have to create a custom DHTML-(div)-dialog, that you could use for IE too. developing a page for IE first and then trying to adapt it to standards-compliant browsers is much more difficult then the other way round ...

showModalDialog is now supported in Firefox 3, but for older versions and other browsers you will need to create your own as gits mentioned.

So that leaves Opera from the major browsers.

[HTML]<title>Popup WebPage</title>
<script language="javascript">
function makePopup(url, width, height, overflow)
if (width > 640) { width = 640; }
if (height > 480) { height = 480; }
if (overflow == '' || !/^(scroll|resize|both)$/.test(overflow))
overflow = 'both';
var win = window.open(url, '',
'width=' + width + ',height=' + height
+ ',scrollbars=' + (/^(scroll|both)$/.test(overflow) ?
'yes' : 'no')
+ ',resizable=' + (/^(resize|both)$/.test(overflow) ?
'yes' : 'no')
+ ',status=yes,toolbar=no,menubar=no,location=no'
return win;

<html><body onLoad="makePopup(syncpop.php', 480, 240, 'resize')" ></body></html>
<? } ?>


window.onbeforeunload = function (evt) {
var message = '';
if (typeof evt == '') {
evt = window.event;
if (evt) {
evt.returnValue = message;
return message;


this code works but not completely...any suggestions??

What do you mean by "not completely"? What doesn't work?

I want the popup window not to get closed ,even on click of the close option untill the time fixed for its display does not gets over.
Using Window.onbeforeunload prompts a dialog box and the window can be closed on clicking the ok button . I dont want it to close .
Any suggestions?

then your best bet is certainly a custom DHTML-popup ... since you even should use it to support all! browsers ... i guess you cannot avoid closing a 'real' window ...

you just have to create a div onclick at whatever you want to open it. use dom-methods like document.createElement('div'); for example. then apply any apropriate css (don't forget the z-index!) to it and append needed elements, like an iframe to load a page or whatever. set a timeout when you need to have it closed after some time ...

another possibility is to create it staticly and set its visibility to hidden, and onclick of the element you need, just toggle its visibility-property.

kind regards

If you want nice-looking popup-divs that have already been written, try GreyBox, ThickBox, SlightlyThickerBox, ShadowBox, iBox or other LightBox clones that support displaying of HTML and not just images as the original LightBox does.
